Embedded electro-permanent magnet magnetic force rotary table of multi-component injection molding machine

Abstract

The invention discloses an embedded electro-permanent magnet magnetic force rotary table of a multi-component injection molding machine. The embedded electro-permanent magnet magnetic force rotary table comprises a rotary table body used for clamping a mold; multiple permanent magnets are embedded into the mold regions of the rotary table body; the permanent magnets on different mold regions can be controlled independently. The embedded electro-permanent magnet magnetic force rotary table has the advantages that the rotary inertia of the rotary table is not increased, and the effective load ofthe rotary table is increased; 2, the molarity thickness of the rotary table is small, the size of the rotary table is small, and the total length of a machine platform is reduced; 3, since the rotary table utilizes electric energy within 1-2 seconds of magnetizing and demagnetization and the mold is attracted by attraction of the permanent magnets without any energy source during work, safety ishigh, high efficiency is realized, and the time for mold assembling and disassembling is shortened substantially.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to an embedded electro-permanent magnetic turntable of a multi-component injection molding machine. Background technique [0002] Multi-component injection molding machines generally have two sets of moulds. Because the two sets of molds are located close to each other, the inner screw holes of the two sets of molds are cumbersome to install due to the close location of the two sets of molds. The mold change time is long and there are potential safety hazards. In view of the above defects, the current common solution is to superimpose magnetic suckers on the fixed plate and the turntable respectively, and use magnetic force to absorb the mold, thereby saving the time of disassembling and assembling screws, and achieving the purpose of quick mold change; but the above solution also has the following defects : Superimposing the magnetic chuck on the turntable will increase the moment of...

[0002] Multi-component injection molding machines generally have two sets of moulds. Because the two sets of molds are located close to each other, the inner screw holes of the two sets of molds are cumbersome to install due to the close location of the two sets of molds. The mold change time is long and there are potential safety hazards.

In view of the above defects, the current common solution is to superimpose magnetic suckers on the fixed plate and the turntable respectively, and use magnetic force to absorb the mold, thereby saving the time of disassembling and assembling screws, and achieving the purpose of quick mold change; but the above solution also has the following defects : Superimposing a magnetic chuck on the turntable will increase the moment of inertia of the turntable, reduce the available load of the turntable, increase the overall length of the machine, and increase the space occupied
